Question

Find out the errors in the following :
int sum (int n)
{ if (n = = 0)
return 0;
else
return n +sum (n); }

Answer 1

"==" is used for char only(for comparisons ).. so here it will be single = sign

Answer 2

Error in the given code snippet:

• In the sum function, the return statement returns the sum of parameter passed with a recursive call to the function.
• As the function sum does not have any provision for decrementing the value, it becomes an endless process of recursion and no meaningful value is returned.
• We can use any loop so that the value of n can be incremented or decremented to make the code snippet error free
